1. Use bigger buffer for transfers - 64kb is the default size
for push, so let it be the same in streaming
2. Use abb when it's available for lower overhead
3. Add a posix_fadvise() on the source APK
4. Increase buffer sizes for the socketpair that's transferring
the data from adbd.
Overall this saves about 25% time for streaming installations
and makes it faster than the legacy push (at last!)

Move the logic for retrofit DAP to its new function. The new flow
in NewForUpdate is:
metadata = ReadMetadata();
if (retrofit dap) UpdateMetadataForOtherSuper(metadata)
return metadata;

kDefaultGroup is the 'default' group that is never deleted
and has no size constraints. During a virtual a/b update,
the following series of action happens:
- move partitions out of groups that will be shrunk / deleted
(into default)
- shrink / delete these groups
- grow / add other groups
- move those partitions to their destination group.
Otherwise, the metadata is inconsistent.

It is hard to re-use this function in the merge code when it forcefully
unmaps the snapshot, because the snapshot may have been rewritten to be
a dm-linear device. Instead, leave the decision up to the caller.

Use dependency injection so that GetProperty / GetBoolProperty
can be mocked in tests.

Previously, we were calling acquire_one_transport with all empty
parameters, which would work when only one device is connected, but fail
when there are multiple. We've already acquired a transport and put it
into the socket as part of the forward request, so just use that
directly.

Change its type from std::string to constexpr char[] so that it does
not need to be constructed at runtime, which pollutes the bss page
unnecessarily.
Bug: 138856262
Test: Along with another fix for libbootloader_message.so, see that bss
section for libbootloader_message.so is now clean on cuttlefish
for several processes.

Add support to specify module parameters in LoadWithAliases. These
parameters will be appended to any which are specified for the module in
modules.options.

Add a remove method which will unload a given module from the kernel,
along with any modules it depended on, assuming those modules are now
unused.
